动物药麝香、牛黄、蟾酥多年来被认为是抗心绞痛复方配伍中的基本主药。有关这些药物抗心肌缺血作用方式以及能否直接改变缺血区心肌功能,至今尚未证明。本工作通过心肌局部力学分析理论,借籍心肌节段长度和冠状动脉液压阻断技术,对狗多种循环变动条件下的心肌运动特征作了分析,阐明了节段长度△SL、ML、EDSL、SS参数与急性缺血、前后
Animal medicines such as musk, bezoar and osmanthus have been considered as the basic medicines for the combination of anti-angina pectoris for many years. The way these drugs are resistant to myocardial ischemia and whether they can directly alter myocardial function in the ischemic region have not yet been demonstrated. In this work, through the analysis of myocardial local mechanics, the length of myocardial segments and coronary arterial hydraulic blockade techniques were used to analyze the characteristics of myocardial motion under multiple cyclic changes of dogs, and the segment lengths ΔSL, ML, and EDSL were clarified. , SS parameters and acute ischemia, before and after
